Concord C1 Biretrograde Limited Editions

Concord C1 Biretrograde

Concord has released new limited edition models in the C1 line featuring retrograde day and date displays. The 44mm x 14.6mm case is available in 18K rose gold (150 pieces) and platinum (50 pieces). The day display is located at 7 o’clock, and the date at 4 o’clock. The automatic movement is a Concord C101 by La Joux-Perret offering a 42 hour power reserve. Below the 3.3mm thick anti-glare sapphire crystal lies a skeletonized and translucent multi-layer dial.

The slightly off-center chapter ring sits on a sapphire disk above the gear trains. An opening at 12 o’clock reveals the balance. The applied luminescent hour markers float above the movement, resting on the crystal dial. The retrograde cam system is also visible. The movement combines finishes including black chemical treatment, circular graining, Côtes de Genève, and matte or glossy polish.
